Wow that's amazing how you've been able to get pregnant so quickly after your laps after not having success for so long! Definitely gives me and others hope.
Good on you for pushing to have it investigated rather than just continuing with IVF. My FS luckily is very good and very results focused so did recommend a lap and said she definitely wouldn't recommend endless rounds without further investigation. I'm glad to have decided to do the lap first before going down the IUI or IVF path. Want to maximise my chances first, and I might even get lucky naturally like you!
I was lucky she was very supportive and happy to refer me on to my surgeon too. Especially since she could have done the lap (given it was only a possible suspected case at that stage).
So I'd definitely recommend that if a women suspects endo could be likely, then make sure you push for that referral to an expert endo surgeon, it's well worth at least another opinion!
